JESSE w. MARTIN, or FRIENDSHIP, TENNESSEE, AssIsnon or ONE-HALE TO s res ivu rtrm, or FRIENDSHIP, TENNESSEE.

T 0 all whom it may concern Be it known that I, Jnssr. IV. MARTIN, a citizen of the United States, residing at Friendship, in the county of Crockett and State of Tennessee, have invented certain new and useful Improvements in Coin Separators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in coin separators and has for an object to produce a compact apparatus for the quick and efficient separation of heterogeneo-us coins into their various denominations.

It is another object of the invention to provide a machine which will effect this separation of coins in a minimum of time, accurately and with the expenditure of little manual effort.

A further object ofthe invention lies in providing a simple, inexpensive device for carrying out the above described purposes which will be of small size and yet have a comparatively great capacity for the coins to be separated.

With the foregoing and other objects in view, the invention will be more fully de scribed hereinafter, and will be more particularly pointed out in the claims appended hereto. 7

Referring more particularly to the drawings, the device embodies generally a framework and a cabinet within the framework with operating means for causing the reciprocating and, oscillating movement of the cabinet, within-which are provided a number of coin trays having openings of varying sizes in theirbottoms to permit a sifting Fig. 3 is a top plan view of the coin sepa- COIN SEPARATOR.

action of the coins and their subsequent separation into the respective trays.

The framework iscomposed ofa base 1 from which extend. front uprights or standards 2 and 8 and rearstandards l and 5. Beams 6 and 7 are secured between the pairs of front and rear standards, and cross rails 8, and 9 are secured between front and rear standards at the top of the framework. Guide rails 10 and. 11 at the bottom, and 12 and 13 at the top are secured'a-long the sides of the framework to receive lower and upper sets of rollers 14 and 15 respectively carried by the sides of the cabinet which is designated generally at 16. At its bottom the as I cabinet 16 is provided with two sets of rollers 17 and 18 adapted to roll along the imperforate base 1.

The cabinet 16 is closed on all sides and also on the top and bottom and is accessible through a door 19 hinged at the front as indicated at 20, and provided with a latch 21 pivoted at 22 on the front face of the doorand adapted to slip in a catch 23 on the front of the cabinet adjacent the free edge. of such door. The latch 21 oscillates in a strap- 24; aflixed to the door 19 and is urged downwardly'into contact with the catch 23 by a fiatspring 25 also secured to the door. A turn button 26 having a cam portion 27 adapted to engage beneath the latch 21 is employed to lift the latch against the influence of the spring 25.

Within the cabinet are guide strips 28 and 29 placed one above another at suitable intervals, being so arranged to receive sliding drawers 30 which are provided in any suitable number, for instance six such drawers are shown in the drawings as provided to receive silver dollars, half dollars, quarters,

nickels, pennies and dimes in the order mentioned. These drawers or trays are formed with openings 31 in their bottoms of vari: ous sizes to agree with the coins that are intended to pass therethrough. For instance, the openings 31 in the uppermost drawer or tray 30 are large enough to permit coins of" being hali dollars. Each of the trays is preferably formed with a knob 32 to permit of its ready withdrawal. In the top" of the cabinet is secured a hopper 33 accessible for placing coins therein through the opening between the top rails 8 and 9 of the framework.

As shown in Fig. 5, a rack 34 is afliXed to one side of the cabinet 6 and is adapted to mesh with a mutilated pinion 35 on a shaft 36 journaled in a beam 37 affixed to a suitable part of the framework. The shaft 36 may be rotated manually through a crank 38 projecting beyond the exterior of the framework. This rack and pinion are intended to advance the cabinet forwardly or outwardly toward the left as shown in Fig. 5.

A coil spring 39 connected between beams 40 and 41 secured respectively to the back of the cabinet 16 and the framework, serves to draw the cabinet rearwardly in the opposite direction when the mutilated pinion 35 moves out of engagement with the rack 34. Coil spring checks 42 and 43 are secured to beams 44 and 45 respectively carried at the rear end of the framework, and these spring checksor stops are arranged in the path of the upper and lower portions of the cabinet 16. The lower stop 42 is preferably of a greater length than the upper stop '43, and the lower stop 42 is also pref-v erably wound of larger turns and heavier spring 'material so that it will catch the lower part of the cabinet and tend to oscillate or tiltthe cabinet so that its upper rear end may strike the top check 43 which will of course tend to return the same in'the opposite direction or tend to right the cabinet.

The lowermost portion of the cabinet is also provided with rails or sills 46 and 47 tending to close the base at this point to avoid the entrance of foreign material which mightotherwise get beneath the cabinet and impede the action of the rollers 17 and 18.

In use, a heterogeneous assortment of coins is dumped in through the hopper 33 and accumulates in the uppermost tray 30. The crank handle 38 is then put in motion which causes the mutilated pinion to first engage in the rack 34 and shift the cabinet 16 outwardly toward the left in Fig. 5 until it reaches the limit of this movement, whereupon the pinion 35 will move outof engage ment with the rack 34 and release the cabinet to the action of the return spring 39. This latter spring, however, having been distended by the outward movement of the cabinet act t'o violentlydraw such cabinet to the rear and brings the lower rear por tion of the cabinet forcibly against the lower projecting check spring 42 resulting in the cabinets being abruptly arrested.

The action is such as to tend to force the cabinet off its balance and make it swing about the rear roller 18, the upper portion of the cabinet swinging back and striking the upper check spring 43. This latter. spring will of course impart a rebounding movement to the cabinet restorin it in the opposite direction. I

T he cabinet, during all of this movement, rolls easily and responsively within the framework on the rollers 17 and 1 8, and likewise the correct position of the cabinet is always preserved by the side rollers 14 and 15 coming in contact with the guide rails or sills, all the time yielding the greatest freedom of movement without any appreciable friction. This violent reciprocating movement and abrupt checking of the cabinet causes the coins to be shifted across the openings 31 in the trays so that such of the coins as are smaller than the openings may pass therethrough and fall into the next lower tray, where theoperation is repeated and this action is only necessary for a few seconds before all of the coins will be properly assigned to their various trays. The oscillating action afforded by the check springs 42 and 43 is very important inasmuch as it causes the bottoms of the trays to assume an inclined position creating a tendency in the coins to slide therealong and thus be properly presented to the openings.

After the progress of the sorting has been discontinued, the door 19 is opened and the various trays may be drawn outwardly with the coins separated into their various denominations. The empty traysare then replaced and the apparatus is in condition for subsequent action.

It is obvious that various changes and modifications may be made-in the details of construction and design of the above specifi= cally described embodiment of this invention without departing from the spirit there'- of, such changes and modifications being restricted only by the scope of the following claims.
